Donald Trump appealed to blue collar workers by rallying against free trade deals. The one deal he constantly highlighted was the deal George Bush senior negoitated - NAFTA.

With him now sitting in the Oval Office, will Donald Trump keep his promise to working Americans, or will he flip-flop instead? Only time will tell.
